Deli Railway Station: Take the red line metro (M2) and travel till Dek Ferenc square (4th stop). There you can get on to the blue line metro (M3) (toward Kőbnya Kispest) and get out at Klvin tr (2nd stop).

The easiest way to find the hostel from Klvin tr:
You come up on the escalator when you get off from the underground, and with the escalator opposite way up you come out. You come round on the zebra right then, directly long beside the building operations and in this manner Rday you arrive into a street, which is parallel to our street,. You turn right on the first street from there, and from there the first street leftwards will be Lnyay utca, our street. We are on the street's right side, 9. street-number, Delicatesse gate beside a shop. 5 doorbell ours, where nothing is announced yet.
All of the road from the underground there are not more 5 minutes, only somewhat more complicated now because of the building operations.
